Calling a JAX-WS RI 2.2 service from Tomcat6 with java6

I am trying to access a JAX-WS 2.2 service from Tomcat6 with Java6. For what I have researched there is a problem with this, as Java tries to use first some of its default javax.xml.ws libraries which doesn't have the WebFault.messageName method. So it fails with this error:
GRAVE: javax.xml.ws.WebFault.messageName()Ljava/lang/String;
java.lang.NoSuchMethodError: javax.xml.ws.WebFault.messageName()Ljava/lang/String;
at com.sun.xml.ws.model.RuntimeModeler.processExceptions(RuntimeModeler.java:1162)
...
The solution seems to be creating an "endorsed" directory in JAVA_HOME/jre/lib/ (or in TOMCAT_HOME) and putting there the required libraries.
However, some people say the library needed is webservices-api.jar, for example, here (#Issue 3):
https://www.fromdev.com/2010/01/trying-to-run-jax-ws-sample-application.html
And other people talk about jaxb-api-2.2.jar and jaxws-api.jar, for example here:
Grizzly - java.lang.NoSuchMethodError: javax.xml.ws.WebFault.messageName
I have downloaded all three of them and placed them in both directories (inside JAVA_HOME and TOMCAT_HOME).
My problems:
· I have no issues accessing this service from a standalone java6 application, both from Netbeans or running the .jar from command-line, it fails only from Tomcat. So I am not sure if the stated above is the cause of my problems. Because, shouldn't it also fail from command line?
· I am not being able to test the above solutions, because Tomcat does not seem to know the "endorsed" directory. When I run this in the standalone application:
System.out.println(System.getProperty("java.endorsed.dirs"));
It prints:
/usr/lib/jvm/jdk1.6.0_45/jre/lib/endorsed
However, Tomcat prints a blank line.
I have tried to modify tomcat6.conf, with this (and restarting, of course):
JAVA_OPTS="-Djava.endorsed.dirs=/usr/share/tomcat6/endorsed -Djavax.sql.DataSource.Factory=org.apache.commons.dbcp.BasicDataSourceFactory -Djava.awt.headless=true -Xms1024m -Xmx1024m -XX:PermSize=1024m -XX:MaxPermSize=1024m"
But it still doesn't seem to know that property.
So, how can I tell Tomcat where the endorsed directory is located? Do you think that my problem can be another than the stated, as it works from a standalone application?

So, the solution:
Do you think that my problem can be another than the stated, as it works from a standalone application?
No, that was exactly the problem.
how can I tell Tomcat where the endorsed directory is located?
It seems that setting this option in tomcat6.conf:
-Djava.endorsed.dirs=/usr/share/tomcat6/endorsed
is not enough. It is required to create a variable called JAVA_ENDORSED_DIRS. So these two lines are needed in tomcat6.conf:
JAVA_ENDORSED_DIRS="/usr/share/tomcat6/endorsed"
JAVA_OPTS="-Djava.endorsed.dirs=$JAVA_ENDORSED_DIRS [-Djava....]"
Not really well documented issue, I think.

Vert.x fails to "Run your module and see your changes immediately"

I am working with the Vert.x Gradle template hosted at the Vert.x Github space.
The build file suggests that there is a runModIDEA target that runs IDEA-built class files so that rebuild/redeploy is not required to pick up changes:
runModIDEA - run the module from the project resources in IDEA. This allows you to run the module without building it
first!
... yet the task does not exist per ./gradlew tasks.
I am not tied to this particular build task per se.
I just want a working auto-redeploy solution that enables me to see updates without a two minute rebuild/redeploy cycle.
EDIT: I also tried running it directly, pointing to InteliJ IDEA output classpath. It works fine, but doesn't pick up changes.
vertx runmod com.mycompany~vert-x-reverse-proxy~1.0.0-final -c conf.json -cp out/production/vert-x-reverse-proxy
EDIT: I also tried ./gradlew runmod -m, first changing vertx_classpath.txt so that the IDEA files (out/production) are looked at first. Still no redeploy. In fact, while it was running, I deleted the out directory and it continued working.
EDIT: I also tried vertx run com.mycompany.myproject.ReverseProxyVerticle -c conf.json -cp out/production/vert-x-reverse-proxy... same results. It ran as expected but did not pick up changes. Only way to pick up changes was to gradlew clean and re-assemble.
EDIT: I have been through these instructions as well.

For anyone who stumbles upon this question, I had the same problem and managed to fix it by deleting everything under the /mods folder in the /target directory. This is in fact mentioned in the vertx documentation - though maybe could be a little more emphatic. Once everything under /mods is removed, start up the application and it redeploys whenever anything is changed.

If you are new to vertx and stumble with this problem or similar, it might be worth to have a look at this vertx google group entry. It describes the changes that need to be done to the generated project by the Vertx Gradle Template to get it running.
I know, this does not answer directly the question posted here but I hope it helps you further.

Matlab and JDDE

Update: The problem was solved with the help of MathWorks. I've published the answer below.
I need to control a program (Zemax) from Matlab. Unfortunately, Zemax only supports DDE for such control, which Matlab does not support any more. It works, but stops working on 64 bit platform after a few (presumable 63) DDE calls.
I wonder if there are working solutions. I could probably program a DLL with correct DDE support and then use DDE in Matlab via this DLL. This is a major effort for me. A more suitable solution would be to use Java DDE methods. Following another post here, I've discovered the JDDE library. However I cannot make it work: Even if I am in the directory with the DLL and JAR files, executing
import pretty-tools.JDDE-2.0.3.*
works fine but calling
a = com.pretty_tools.dde.client.DDEClientConversation()
afterwards (as done here) results in
Undefined variable "com" or class "com.pretty_tools.dde.client.DDEClientConversation".
I have very limited writing privileges on my PC, so I have added the javaclasspath.txt file with the jar/dll location to the directory indicated by prefdir. The file looks like this:
C:\Users\xxxxxxxx\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
Calling javaclasspath shows a long listing with the last lines being:
...
C:\Program Files\MATLAB\R2012b\java\jarext\webservices\ws_client_core\mw-service-client-core.jar
C:\Users\kkarapet\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
DYNAMIC JAVA PATH
<empty>
So path seems to be set correctly. What am I doing wrong?

With the help of MathWorks support, I've found the answer. Here is how to make JDDE work with Matlab 2012b, without admin privileges:
Download and unpack JDDE files (DLLs and JAR) into some folder. Let's say it's $path-to-jdde$\.
In Matlab, type prefdir. Open the resulting directory and create two files there, javaclasspath.txt and javalibrarypath.txt.
In javaclasspath.txt, add $path-to-jdde$\pretty-tools-JDDE-2.0.3.jar.
In javalibrarypath.txt, add $path-to-jdde$\.
Restart Matlab.
Now call ddeConv = com.pretty_tools.dde.client.DDEClientConversation; and start using the created object as described in JavaDoc. E.g. to connect to Zemax, run Zemax and then in call ddeConv.connect('Zemax', 'abc').
Step 2 above can only be done starting Matlab version R2012b. With an older version, if you have the write rights on the Matlab installation directory, you should be able to replace step 2 by editing the files librarypath.txt and classpath.txt in $MATLABROOT$\toolbox\local. I could not verify it so if you confirm it please let me know in the comment below.

Debug Lua in a Java project using LuaJava

My project has LuaJava as the script interpreter, for usage in both desktop and android via AndroLua. I want to be able to debug it, but I'm unable to arrange it.
I have tried with an Eclipse plugin, Koneki, which is poorly documented and only seems able to debug Lua-only projects. I tried doing as the tutorial but it doesn't accept my project as valid for not having lua capabilities. I tried then using a secondary project linking my Lua files, launching the debugger and then my project, but the process does not attach. I tried using the methods provided by the tutorial but they throw an "non-existing Lua method" error.
I have also tried Decoda, but despite being able of launching the executable no symbol pdb files exist so the breakpoints are not triggered.

After contacting ZeroBraneStudio's creator, it is now posible to debug AndroLua and LuaJava on his IDE.
Instructions here. This functionality is available from v0.38 onwards.

I use koneki and it works a treat for lua embedded in c/c++/objective c - it should work for luajava but haven't tried it. Whats the message you get in Koneki, there are a few things you need to setup. In particular lua socket in your path, and the debugger.lua in your LUA_PATH.
These lines in your first lua file loaded
require "socket"
local initconnection = require("debugger")
initconnection("127.0.0.1", 10000, "luaidekey")

How to fix a NoClassDefFoundError?

I haven't worked with Java in about 10 years, so it's very probable I'm doing something elementary wrong here...
I am writing a "server-side extension" for SmartFoxServer (SFS). In my login script, I need to make a connection to MS SQL Server, which I am attempting to do using JDBC. I have tested the JDBC code in my debug environment, and it works fine.
BUT
When I put the server-side extension in the SFS "extensions" folder (as per spec), I'm getting a NoClassDefFoundError thrown - clearly SFS can't find the required JAR (sqljdbc4.jar). I have tried putting this JAR in my classpath; I tried including it in my Eclipse project - but for some reason, SFS adamantly refuses to accept the existence of this JAR.
What am I doing wrong?

I have no experience with the product you mention but many years of Java experience.
Have you tried putting the sqljdbc4.jar in the same location as your server-side extension (the extensions 'directory') ? You will likely have to restart SFS after this.
